I'm worried about my 26 mo DD's behaviour which has changed drastically over the last couple of weeks. She's always been a little on the shy side but it's gotten much worse lately. If I take her somewhere like the library, park etc, she wants me standing right next to her and will cry 'Mummy coming, mummy coming' if I don't go immediately over. I've taken her to friends houses, where she has been before, and she is sooo clingy - when I try to talk to my friends she'll try and hit me every time I say something (and we'll have to leave because she gets so upset). It's like she wants all the attention on her. We've had friends here for a BBQ and she refuses to come on the balcony where we are, but screams if we leave her in the adjoining room with toys, TV etc. Shes taken to sometimes refusing to get in her car seat or pram when we're out and I can't physically get her into them. She would like to be at home the whole time with just her and me (and maybe DH). It's a bit isolating! She's also started throwing some major tantrums at home, but I was expecting that to start.
The only things which have changed are: I'm 24 weeks pregnant (and have been quite sick with it although a lot better now), and she's been teething her 2nd molars quite badly (3 are fully through now, and the last one is half way through). Could this explain anything or is this just the terrible twos? I'm finding it difficult to know how to discipline her because if it's because she's in pain or unsure because of the pregnancy, I don't want to be too hard on her.
Any ideas of what I can do to help/reassure her? She has a large vocab but talking and explaining things to her doesn't seem to help much.
